Thanks! Just found the info I needed in debug.log. That helped a lot.

Trying to figure that out too. When I check with higher block counts, it keeps returning false with the error: null. Just ran it with 4 and 500 blocks. No clue what's going on.

That actually worked! But here’s the kicker when I run verifychain, it always says true, except for when I set nblocks=0 to check all blocks. Then it goes false. Is this a timeout issue or something?

I'm on Ubuntu and can’t figure out how to use the -verifychain option with bitcoin-cli. Works fine with curl but typing it directly isn't clicking for me. I know it needs two parameters, but where do I put them?

Totally makes sense. The snap method and the manual install aren’t giving the same results. I re-did it with the daemon method and it works now.

I think I messed up the snap install. I went through the Ubuntu Software instead of following a manual install. Gonna check that out later.

I saw something about that on Reddit. It talked about setting up data directories for systemd. The symlink in /snap/bin looked interesting too.

Yeah, there’s a line in the systemd file for bitcoind. But is that just a script or should it be an executable? Tried to move it to /usr/bin/bitcoind and got some error 203.

That’s cool, but what about the actual bitcoin-core executable? Like, how does it know what to run then?

Just set up bitcoin-core on my Ubuntu. It's version 25.0 and I’m wondering where all the files land after the install. Anyone know?

Thanks for the reply! So, I had a sudden power cut while loading the blockchain. When I rebooted, bitcoind wouldn’t start. I'm thinking of writing a script to check if my local blockchain data is intact at startup. If…

Following up on that, I tried renaming blocks in the blocks and chainstate folders. Got a startup error from that. So, if anyone wants to create a corrupt database for testing, looks like that method works.

My computer crashed the other day and it messed up a block. I had to rerun bitcoind with -reindex to fix it. Now I'm trying to figure out how to intentionally corrupt the chain or database for testing. Just cutting the…
